How to Make Your Own Fossil Eggs

Last week our class made Fossil Eggs.  Kereru are going to bury them in the sandpit for us tomorrow and we will dig them up and then excavate our dinosaurs.  Next week for homework we will write a mini-report about our dinosaurs.

Here is the recipe for Fossil Eggs if you want to make them at home.  At school we used a cup of Plaster of Paris to make them set extra hard, but you may not have that to use at home.

You will need:
  • 1 1/4 cups dirt
  • 1 1/4 cups of flour
  • 3/4 cups salt
  • 1/2 cup sand
  • Water
  • Plastic Dinosaurs
How to make dinosaur eggs:
  1. Mix together dirt, flour, salt and sand.
  2. Slowly stir in water to create a dough, clay-like texture.
  3. Mould the dough around one of the plastic dinosaurs.
  4. Let the eggs dry thoroughly. This may take all day or several days depending on the weather.
